[0002] A sensor is a detection device that senses the information being measured and, according to certain rules, converts it into an electrical signal or other desired form of information output to meet the requirements of information transmission, processing, storage, display, recording, and control. The existence and development of sensors have given objects senses such as touch, taste, and smell, bringing them to life. Sensors are an extension of the five human senses.

[0003] In ocean detection, microwave ocean sensors are needed to detect and explore the ocean environment. Microwave ocean sensors are equipped with shielding covers to shield the internal circuits from the effects of external electromagnetic waves and the outward radiation of internally generated electromagnetic waves. Existing shielding covers generally place metal sheets or aluminum foil behind or on the sides of the microwave sensor, but the shielding effect is not thorough enough and cannot protect the sensor.
